Where can I return my unwanted alcohol? ie Supermarket/other shops

I have a few bottles of alcohol (whisky, rum etc) that I have amassed either as as gifts or that were brought to a party I had a few weeks back and I was wondering whether anyone knew any shops that would be willing to take them back even though I have no receipt/s as I will never drink them myself.

I know its a bit cheeky to try to return them somewhere they were never bought but if I could return them and receive supermarket vouchers in exchange for them then no-one loses out do they?
